FT-IR
Infrared Spectroscopy is one of the methods focused on the chemical analysis of materials. Unlike X-ray Photoelectron Spectroscopy (XPS), it is not focused solely on surface composition and does not quantitatively determine the elemental composition, but it is capable of detecting certain types of chemical bonds.
At our department, we have $\text{FT-IR}$ spectrometers available: an Equinox 55 (Bruker) in the IR-RAS configuration with the possibility of external beam output for in-situ measurement during the deposition process, and a Nicolet 6700 with an $\text{ATR}$ accessory, which allows for the measurement of infrared absorption spectra of materials in solid and liquid states.
Basic Technical Parameters:
- Spectral range: 500 to 4,000 cm-1
- Resolution: 0.5 to 32 cm-1
Available Accessories:
- Accessories and cells for measuring spectra in transmission (films, liquids, KBr pellets).
- Cell for measuring single-reflection ATR spectra on a ZnSe crystal at room temperature.
- Thermostated cell for measuring single-reflection ATR spectra on a diamond crystal in the temperature range of 20 °C to 200 °C.
- Thermostated cell for measuring liquid samples in transmission in the temperature range of 20 °C to 200 °C.
